Interpretation: A reaction taking place in particle accelerators is given. The energy change for the reaction is to be calculated. Whether the energy is released or absorbed and the possible source for this energy is to be identified.
Concept introduction: In a nuclear fission, two light nuclei combined to form heavier nuclei. In a nuclear reactor, a self-sustained fission chain reaction occurs and energy is released during the process.
To determine: The change in energy for the given reaction; whether the energy is released or absorbed and the source of energy.
